HOW TO COMPUTE LATEST FINISH TIME FOR EACH NODE (L)

The steps involved in the computation of Latest Finish Time for each node (LF) are as follows:

Step 1→ Identify all the activities leading back to each node.
Step 2→ Calculate the sum of expected time of each set of activities leading back to each node.
Step 3→ Calculate the maximum of sum of expected time of each set of activities (as per step 2).
Step 4→ Calculate latest finish Time by taking out the difference between critical path duration and the maximum of sum of expected time (as per step 3).

The aforesaid calculations may be presented in the form of following table:
